Etude des propriétés thermiques structurales, magnétiques et électriques d'alliages Ni-P électrolytiques : modélisation magnétique

Abstract : The working out of Ni (1-x)Px alloys has been led by keeping all physical and chemical parameters except the phosphorus composition into the bath with aview to obtain electrodeposed specimens which can be reproduced in a large composition field. Analyses of thermal and structural properties made it possible to determine the structural relaxation and define the different crystallization processes observed during annealingtreatements. First, magnetic properties have been analysed under a constant magnetic field determining the specific magnetization in relation to the temperature as the Curie temperaturein relation to the composition. Then, under a constant temperature (4,2 K or 300 K) a systematic study of our, untreated specimens for manufacturing and annealing treatment allowed to define the variation of the different magnetic sizes such as the saturation moment, the coercitif and the remanence depending on the composition electrical transport properties have been qualitatively analysed between 25°C and 500°C from the electrical resistivity and its coefficient, defining thus some structural and electrical modifications
